Procurement Notes

Verify the specific ordering suffix to confirm exact capacitance tolerance and termination style before procurement. Confirm that the M5 threaded interface matches the mounting panel specifications. Ensure the voltage rating and current capacity align with the circuit requirements. Check RoHS compliance status if environmental regulations apply. Validate the datasheet version for any recent design changes or discontinuation notices.

Selection Notes

Select this component when axial mounting and direct panel penetration are required for optimal grounding. Consider the 10 A current rating for power distribution lines. The X7R dielectric offers stable performance under varying conditions. Evaluate the physical size constraints against available chassis space. Compare against similar series parts for alternative capacitance values if needed.
